T HIS CHAPTER INTRODUCES YOU to Visual Basic for Applications (VBA). VBA is
Excel’s programming language and it is used to automate various aspects of
Excel — including charts.

VBA in a Nutshell
VBA is best thought of as Microsoft’s common application scripting language. VBA
is included with all Office 2002 applications, and it’s also available in applications
from other vendors. You use VBA to write procedures, frequently known as macros.
Following is a quick-and-dirty summary of what VBA is all about.
You perform actions in VBA by executing VBA code.
You write (or record) VBA code, which is stored in a VBA module.
VBA modules are stored in an Excel workbook, but you view or edit a module
using the Visual Basic Editor.
A VBA module consists of procedures.
A procedure is basically a unit of computer code that performs some action. Here’s
an example of a simple Sub procedure called Test. This procedure calculates a
simple sum and then displays the result in a message box:
Sub Test()
Sum = 1 + 1
“”
377
MsgBox “The answer is “ & SumEnd Sub
